I have no problem with a person wanting a “Child free flight”.
Let them pay extra for it.

Take a family flight, pay the regular price.
Take a “child free” flight, pay premium for the privilege.

Awww Jeez.

There you go being reasonable.

There's some justification for higher costs, for adults-only flights. Children tend to weigh less than adults — therefore, an adult-only flight would probably have less capacity for freight, or have to burn more fuel.
